Complacency Is Over....... "Cancel All Orders, Cancel All Orders....."

I hope he has "survived" the trading day.... If you want a good explanation how the "surprising" market action could happen at you should read NO FAT FINGER! & "Rise ( & Fall ) Of The Machines" ... ... If my market view is correct i think we can enjoy similar clips in the future.........

Bleibt zu hoffen das er den Handelstag gesund überstanden hat....Mehr Hintergründe für das nicht wirklich überraschende Marktverhalten gibt es in NO FAT FINGER! & "Rise ( & Fall ) Of The Machines" ... Sollte ich mit meiner Marktbeurteilung recht behalten dürften uns noch einige solcher unterhaltsamen Videos ins Hause stehen....

Did he really cancel his orders near the bottom..... ;-)

Hört sich für mich so an als wenn er nahe dem Tief alle Orders gecancelt hat...... ;-)

"Rise ( & Fall ) Of The Machines" ...

With volatility finally creeping back into the markets i think the "Rise Of The Machines" aka the QUANT story is deserving extra attention....Especially with market stats shown in Does Anyone Detect A Hint Of Complacency? from 2 weeks ago..... Make sure you also read the UPDATE....

Ich denke das dank der etwas gestiegenen Volatilität das Thema ROBOTRADING aka QUANTS einen ganz genauen Blick wert sein sollte....Das gilt umsomehr als das noch vor 2 Wochen ein kollektiver Realitätsverlust ( siehe Does Anyone Detect A Hint Of Complacency? )die Marktteilnehmer erfasst hatte.... Verweise ausdrücklich auf das UPDATE......



The Minds Behind the Meltdown WSJ

How a swashbuckling breed of mathematicians and computer scientists nearly destroyed Wall Street

Instead of looking at individual companies and their performance, management and competitors, they use math formulas to make bets on which stocks were going up or down.

By the early 2000s, such tech-savvy investors had come to dominate Wall Street, helped by theoretical breakthroughs in the application of mathematics to financial markets, advances that had earned their discoverers several shelves of Nobel Prizes.

PDT, one of the most secretive quant funds around, was now a global powerhouse, with offices in London and Tokyo and about $6 billion in assets (the amount could change daily depending on how much money Morgan funneled its way). It was a well-oiled machine that did little but print money, day after day.

That week, however, PDT wouldn't print money—it would destroy it like an industrial shredder.

The market moves PDT and other quant funds started to see early that week defied logic. The fine-tuned models, the bell curves and random walks, the calibrated correlations—all the math and science that had propelled the quants to the pinnacle of Wall Street—couldn't capture what was happening.
At the time, few quants realized what was happening, but over the next few days a theory would emerge: The U.S. housing market was unraveling, leading to big losses in the mortgage portfolios of banks and hedge funds

The result was a catastrophic domino effect. The rapid selling scrambled the models that quants used to buy and sell stocks, forcing them to unload their own holdings.

Authorities, meanwhile, had little idea about the massive losses taking place across Wall Street.
That Tuesday afternoon, the Federal Reserve said it had decided to leave short-term interest rates alone at 5.25%.Investors on Main Street had little idea that a historic blowup was occurring on Wall Street.

Oddly, the Bizarro World of quant trading largely masked the losses to the outside world at first. Since the stocks they'd shorted were rising rapidly, leading to the appearance of gains on the broader market, that balanced out the diving stocks the quants had expected to rise. Monday, the Dow industrials actually gained 287 points. It gained 36 more points Tuesday, and another 154 points Wednesday.
The huge gains in those shorted stocks created an optical illusion: the market seemed to be rising, even as its pillars were crumbling beneath it.
A source of the extreme damage Wednesday and the following day was the absence of some high-frequency statistical arbitrage traders, firms that use high-powered computers to trade rapidly in and out of stocks and can act as liquidity providers for the market.

As investors tried to unload their positions, the high-frequency funds weren't there to buy them—they were selling, too. The result was a black hole of no liquidity whatsoever. Prices collapsed
UPDATE:

Rise of the news-reading machines FT Alphaville

The arms race in trading technology is set to intensify this week as Thomson Reuters, the news and market data company, on Monday unveils a service for “high-frequency” traders allowing them to make split-second trading decisions based on news articles “before the information moves the market” . . .

So-called “machine readable news” services, such as the new Thomson Reuters product, have grown up in parallel with the emergence of high-frequency and algorithmic trading, which depend on lightning-fast delivery of data and news to traders specialising in such computer-driven trading strategies.

Machine readable news systems use computers to “scrub” thousands of breaking news stories, prioritising their relevance for traders – often based on simple key words – and delivering them in a special feed. This provides traders with “signals” that are used to drive their strategies
Chicago Federal Reserve Joins Zero Hedge In Warning Over Threats From High Frequency Trading ZH
A handful of high-frequency trading firms accounted for an estimated 70 percent of overall trading volume on U.S. equities markets in 2009. One firm with such a computerized system traded over 2 billion shares in a single day in October 2008, amounting to over 10 percent of U.S. equities trading volume for the day.
AN INTERVIEW WITH ED THORPE – THE GODFATHER OF QUANTS Pragmatic Capitalist

Thorpe was the first true quant and an enormously successful gambler and hedge fund manager. He covers everything from beating casinos at their own game to the financial crisis, the role quants played in the downturn and even his own desire to be cryogenically frozen. He even provides his personal outlook and his worries that the return of “business as usual” on Wall Street means the next big crash is inevitable

Kass: The Quant Bubble

A must read...... Pflichtlektüre......

"When the music stops, in terms of liquidity, things will be complicated. But as long as the music is playing, you've got to get up and dance. We're still dancing."

Chuck Prince, former chairman and CEO of Citigroup (told to the Financial Times on July 10, 2007).
Kass: The Quant Bubble TSC ( H/T Anti Lemming )

A portion of the sharp rise in several asset classes over the past few months could be the dominance of quant funds that worship at the altar of price momentum (and the self-fulfilling prophecy of the fund flows that follow the price momentum induced by the quants!).

By some estimates, this price-momentum-based quant trading now has doubled in significance since early in the year, to more than two-thirds of the average day's trading.

> I doubt that this figure is correct, but it is verry telling that combined with High Frenquency Trading the "Quants" are the main market force dominating trading...... Doesn´t give me much comfort that the recent gains are "sustainable" ...... Especially after one of the biggest Bear Market Rallies ever on almost non existent Volume ( ! ) ..... Thank god the retail investor this time is smarter than the so called "smart money" ( 13th Straight Week Of Domestic Equity Fund Outflows As Market Rips 11% Over Same Period ) BRAVO ;-)

> Ich bezweifle das die von Kass gennante Zahl in der Tat so hoch ist.... Das aber die Quants zusammen mit dem sonstigen computergetützten Handel ( HFT) der wesentliche "Spieler" ( Investor traue ich mich in diesem Zusammenhang nicht in den Mund zu nehmen.... ) an den momentanen Märkten sind fördert nicht gerade mein Vertrauen in die Nachhaltigkeit in einen nicht "unwesentlicher" Teil der bisher verbuchten Kursgewinne . Nicht verbessert wird das Gesamtbild das der Anstieg praktisch unter minimalen ( ! ) Handelsvolumen stattgefunden hat.. Wenn man jetzt noch bedenkt das wir gerade einer der größten Bear Market Rallies aller Zeiten hinter uns haben sind immer neue Kursziele die man so jeden Tag zu hören bekommt zumindest "mutig"...Glücklicherweise scheint es diesemal so das der "Kleinanleger" sich nicht erneut für das über Jahre erprobte "PUMP & DUMB" begeistern läßt ( 13th Straight Week Of Domestic Equity Fund Outflows As Market Rips 11% Over Same Period ). BRAVO ;-)

Growth of algo trading - Thomson Reuters

Trades initiated by these funds are insensitive to an underemployment rate approaching 18%, signs of an unsteady recovery in housing, the prospects for higher marginal tax rates and how we are going to finance our budget deficit, which hurdles ever higher.

If you don't believe me about the growing quant fund influence, speak to any prominent institutional trader or salesman: They will tell you that their business with plain vanilla institutions is weak and that the quant funds are the ever growing whales of trading.

The pattern is all-too familiar as a new marginal buyer of an asset class dominates the market until they don't.

Here is an anecdote that underscores the changing landscape and is reminiscent of other sectors hiring at tops. (To refresh your memory, this occurred several years ago in private equity and was followed by a sharp cyclical decline in private-equity deals.) At any rate, a subscriber wrote me a telling note recently about his son's friend who attends Wharton and is "a genius in math and game theory." He was just hired by a high-frequency trading firm after being interviewed by 15 similarly talented employees at the firm. He is 20 years old and has been offered approximately $100,000 a year, with a bonus that can add up to an additional $100,000 a quarter! That's far better than even the estimable Goldman Sachs pays!

Keep dancing if you will, but I continue to sit out the melt-up in stocks and the bubble in other asset classes. When investors/traders are arguably overinfluenced by prices (not fundamentals) that dominate the markets, and are all on a similar side, it has the potential to lead to a treacherous and slippery slope, as it did in 2007-08.

Remember, it is some of the same momentum-based quant funds that sold in March 2009 that have been buying over the past few months
AMEN.....

Hussman "High Loan-to-Value + Trigger Event (Unemployment) = Default"

As predicted..... The comeback of the retail investor has marked the top..... Time for Abby Joseph Cohen to adjust her S&P 500 target of 1050 ( Quote Cohen "Fair value based on recession earnings" ). Wouldn´t surprise me if she will revise it upwards.....Maybe this time her model is based on some Goldman insights of the very strange "Robotrading" ( see also a very disturbing "Robotrading" Chart / WSJ ) accounting for well over 50% percent of overall US equity trading volume lately...... This would be as credible as her/Goldman recession proof earnings call.....;-)

For a "slightly" less optimistic ( aka realitic ) view use your common sense, read a link on my blogroll or just take a look at Doomsville via FT Alphaville..... For a daily dose of excellent "ANTI SPIN" i highly recommend to subsribe to the free daily update from David Rosenberg!!! ( Here are some examplesvia Zero Hedge ). I´m taking a much needed break. So posting on this blog will be very light during the next few weeks.

Wie bereits befürchtet hat zumindets in den USA die Rückkehr der Kleinanleger erneut das Top markiert. Wenn man über Wochen halt jeden Tag vermeintliche "Green Shoots" , lächerliche "Stresstest", astronomisch hohen S&P 500 Ziele, aberwitzige Gewinnausweise die mit GAAP nichts zu tun haben, ein Markt der zu über 50% durch computergestützes Handelssysteme kontrolliert wird ( siehe "Robotrading" bzw. einen wenig vertrauenserweckenden "Robotrading" Chart / WSJ ) usw. vorgesetzt bekommt fällt es einigen Anlegern oftmals schwer den gesunden Menschenverstand walten zu lassen bzw den Überblick zu behalten...... Freue mich jetzt schon auf die Revision von Abby Joseph Cohen und Ihrem S&P 500 Ziel von 1050..... Nur gut das bereits dieses Ziel den Fair Value anhand von Rezessionsgewinnen ermittelt hat. ( Zitat Cohen "Fair value based on recession earnings" ) .

Für einen etwas weniger optimistischen ( andere würden auch sagen realistischeren ) Ausblick empfehle ich wahlweise mehr auf den gesunden Menschenverstand zu hören, einen der Links auf meiner Blogroll oder Doomsville via Ft Alphaville. Wer die momentan wohl beste tagtägliche Analyse frei Haus geliefert haben möchte der sollte sich hier registrieren lassen!!!! David Rosenberg unterscheided sich nicht erst seit seinem Wechsel von Merrill Lynch zu Gluskin Sheff wohltuend von den üblichen Verdächtigen ( siehe Cohen ). Hier einige Beispiele via Zero Hedge. Ich werde mir die nächsten Wochen eine dringend benötigte Auszeit nehmen. Die Postingfrequenz wird also stark zurückgehen.

Hussman

It is very important to recognize that the increasing unemployment rate is likely to exert a different dynamic in this economic downturn than it has in prior downturns, because of the high ratio of household debt-to-income, and the high ratio of mortgage loan-to-value at present.

In normal downturns, unemployment does trigger a certain amount of loan losses, but the general tendency is for unemployment to behave as a lagging indicator.

In the current cycle, high debt-to-income and loan-to-value ratios create a situation where unemployment can easily be the trigger event for further defaults, and could therefore create a tendency for job losses to lead economic weakness (rather than just lagging it).
> Especially when this time the job picture is looking like this.... And lets not forget these already ugly numbers are based on the (Black Box ) BLS numbers.....

> Besonders dann nicht wenn der Arbeitsmarkt im Vergleich zu anderen Rezessionen so aussieht...... Möchte nur noch darauf hinweisen das slebst dieser Blick noch geschönt ist ( da diese Daten auf den teilweise aberwitzigen Statistiken des BLS basieren )......

bigger / größere Version H/T Calculated Risk

I don't think that the feedback will be strong enough to lead to a self-reinforcing collapse, but I do think that it is naïve to expect that the economy will just “shake off the blues” and roar ahead.

At the same time, bank chargeoffs continue to lag the deterioration in credit. The FDIC notes “The high level of chargeoffs ($37.8 billion) did not stem the growth in noncurrent loans in the first quarter. On the contrary, noncurrent loans and leases increased by $59.2 billion (25.5 percent).
The percentage of loans and leases that were noncurrent rose from 2.95% to 3.76% during the quarter. The noncurrent rate is now at the highest level since the second quarter of 1991. The rise in noncurrent loans was led by real-estate loans, which accounted for 84 percent of the overall increase.”

> Click through some of the charts/tables from T2 Partners or just take a look at this chart showing the crash in CRE and it should be clear that the entire US banking system is insolvent. Very frustrating to see that after 12-18 month into the crisis & trillions of taxpayers money wasted that still no progress ( outside of Goldman Sachs...... ) has been made. But with Bernanke, Geithner & Summers in charge...... Unfortunately the situation in Germany & others parts like China, Europe / Emerging Europe, Dubai / Middle East, Japan etc of the world isn´t much better....... Wouldn´t surprise me if the Depression Index will be quite popular in the coming years...

> Klickt Euch wahllos durch die nachfolgende exzellente Präsentation von T2 Partners oder schaut Euch diesen Chart zum Thema gewerbliche Immobilien an und es dürfte klar sein das trotz aller PR, Spinversuche & Bilanzierungsverrenkungen das gesamte US Bankensystem noch immer heftigst insolvent ist. Das mit Billionen von Steuergeldern bisher nicht mehr erreicht worden ist haben wir in erster Linie Bernanke, Geithner und Summers zu verdanken. Leider spielt Obama ebenfalls eine wesentliche Rolle in diesem Drama. Wer trotz desaströser Vergangenheit dieser Leute weiterhin Vertrauen in die Mitarchitekten der Misere setzt macht sich "strafbar".... Da besonders wir hier in Deutschland aber im Glashaus sitzen und es in anderen Teilen der Welt wie z.B. China Europa / Osteuropa , Dubai / Mittlerer Osten , Japan usw. nicht viel besser aussieht dürfte das Wort der "Depression" früher oder später in starker Konkurrenz zur "Rezession" stehen......Unglücklicherweise besteht dieses Mal eine recht große Chance das der Depression Index zukünftig längere Zeit stark erhöht sein wird......T2 July 3 Whitney Tilson: Why There Is More Pain To Come




> Back to Hussman

Now, note that the $59.2 billion figure is the increase, not the total value, of noncurrent loans for the first quarter alone. In a banking system where total capital only represents 10% of total assets (and even that level only thanks to TARP infusions), 3.76% of total loans in the noncurrent category is not a small figure.
